Hi, Dave.
] Is there anyone in a production environment who, as part of their system
] build process, adjusts the TCP receive window/MSS/etc. on production
] systems?
Increasing it helps, particularly if both ends have the same
setting. Don't forget to enable both RFC1323 and RFC2018 support
if you go beyond the 64K mark. Take a look here for some
(slightly dated *sigh*) suggestions along these lines.

As with anything, don't simply "crank it up to 11" because it can
be done. Plan, tune, measure, repeat. :)
Thanks,
Rob.
